OV9281 External Trigger

1.Which seller did you purchase the product(s) from?
2.The Model number of the product(s) you have purchased?
3.Which Platform are you using the product(s) on?
Raspberry Pi 4B
4.Which instruction are you following?

5.Has your product ever worked properly?

6.What problems are you experiencing?
The kernel driver for the ov9281 provides exposure control but does not a control for manual triggering. Other Arducam modules provide the “trigger_mode” control. Is it possible to add this to the kernel driver? There is an example here but I’m using python for my application so is it possible to access the camera registers from python?
7.What attempts at troubleshooting have you already made?

8.How would you like us to help you?


Sorry for my late reply due to our forum system’s issue. Have you solved your issue?

Feel free to let me know if you need more help.



I’m afraid not. There have not been any changes to the kernel module so the V4L2 trigger mode control is still not present.
